Remarks
Use this method when you maintain cell error text yourself by handling the CellErrorTextNeeded event. Call this method when you change the stored error text for the specified cell. This will invalidate the cell, forcing the DataGridView control to retrieve the updated error text through the CellErrorTextNeeded event handler.
Although you can use this method to update errors for header cells, column header cells do not display error glyphs.
